SPRING JUG-TOP.

SPECIFICATION forming part of Letters Patent No. 274,244, dated March 20, 1883,

Application filed February 12, 1883. (No model.)

To all whom t mail concern.-

Be it known that I, Hon/LER WRIGHT, of county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Spring Jug-Tops; and I do hereby declare the followingto be a full, clear, and exact description thereof', ref- Y erence being had to the accompanying draw ings, forming a part of' this specitication, in which- Figure l is a vertical 'sectional view of my improved spring jug-top closed.` Fig. 2 is a similarfview of it open. Figs. 3, 4, and 5 Iare views of the parts detached.

Like letters of' reference indicate likeparts in each. y

The object of my invention is to secure a springjug-top having, first, the spring entirely concealed from view either when the top is open or closed, and, second, which is capable of being secured in an open position.

My improved top is made with a ring, u,

i having lugs a. for the passage of the pintle of the hinge. Between the lugs a', and separated therefrom by the recesses a2, is a box or casing, c, the purpose of which will be described hereinafter.

The cap b is provided with two lugs, b', which are designed to enter the recesses a2, and are properly bored or perforated for the passage of the pintle f of the hinge. lugs b', and extending up inside of the cover b, is a recess or socket, d, formed by the wall or side d', extending between the lugs and united to the inner surface of the cover. f

The box or casing c is provided with a recess, c', having a straight rea-r side orV abutment, c2, placed back of the pintle of the hinge, the upper edge of which is preferably rounded.

vIn the recess d is a spiral spring, e, the lower or rear end, e', of which is crimped or turned in at the last half'coil, so as to extend across the coil at or near' the center. Placed in the half-coil thus made is a headed pin or core, y, which has a bearing against the end e of the spring,which bearing, by reason ofthe crimping in of the end e', is od' orat the side of the center of the spring. The spring, being in the recess d, bears against the inner face of the abutment c2 and tends to hold the cover b'shut. The smooth head g of the pin or core g bears against the abutment c2 and prevents the latter from Between the top. The placing ofthe bearing head g at one side of the center of the spring and of the bearing-surface c2 back of the pintle of the hinge has the effect of producing a tortional action of the spring, which tends to throw the cover down upon the ring a. When the cover is thrown back into an open position the bearin g-t'ace g passes over the rounded upper edge of the abutment c2 of the box or casing c, and vcomes to a seat or bearing against the straight back side of the latter. to be held in an open position, (see Fig. 2,) the bearingface g of the spring finding a square seat at the backside of the abutment, which prevents it from passing over the upper edge of the same.

The great advantages of my improved spring jug-top consist, irst, in the en tire concealment of the4 spring from view when the cover is either open or closed; second, that the spring is raised up from the ring part, and is not lia'- ble to be reached by the contents of the vessel, as is the case in some spring-top vessels where the spring is secured to the ring; third, that the cover may be secured in an open position without trouble or inconvenience. This is of great advantage not onlyin filling the vessel, but also lin the operation of attaching the to p to glass or earthernware vessels, which attachment is made by the use of cement, in which case it is necessary for the workman to work through the ring a. It is very difficult This causes the cover for this to be done in those spring-tops in whichV no device is provided for holding the cover open.

The spring, being loose in its casing d', and pressing freely against its points of bearing, preserves its resiliency a longer time, and is not liable to get out of order.

This top is easily and cheaply made by casting in suitable molds. It requires no special degree of skill in fitting, and has all the known advantages of spring-tops in addition to thosespecifically mentioned.

IOC,

IlO

The boX or casing c is perforated longitudinally for the passage of the pintle f of the hinge. This constitutes a central support for the latter, which makes the hinge very strong and permanent in its character.

It Will be observed that the spring e is. compressed by the opening of the cover and that the cover is closed by the expansion of the spring. This is effected by making it bear 011 an abutment placed back of the pintle of the hinge. This construction enables me to use a loose spring, and such use necessitates a retaining groove or recess to keep the springin place. The spring should be placed with its disk g at the side next to the seat or abutment c2. The spring is most tightly compressed when it is passing over the edge of the abutment c2, and expands" when it comes to place on its seat either on the front or back side of the abutment. It is made long, so that when putin place it requires to be compressed enough lo hold the cover tightly closed.

This invention is applicable to jugs and pitchers of all kinds, inkstands, jars, and cans. Itis customary noviT to use such jars in putting up maple-Sirup, bakingpowder, and other articles for sale, with springtops, the spring heilig depended upon to hold the cover shutin shipment and while the goods are on the shelves of stores, such cans being the package in which the goods are sold.

What Ilclaim as my invention, and desire to secure by Letters Patent, is

l. The combination, in a spring jug-top, of a cover pivoted to the neck-ring and provided with a casing or recess for the reception of' a spring, with a ring-section having a suitable bearing-surface back of the pivot of the hinge, against which the spring bears, substantially as and for the purposes described.

2. 1n a spring jug-top, a cover pivoted to the neck-ring and provided With a spring,- in combination with a ring-section having a suitable bearingfor the spring back ofthe hinge, Whereby the opening of' the cover compresses the spring and causes it to act against the cover, substantially as and for the purposes described.

3. The combination, in a spring jug-top, of arin g-section havin g three 'pintle-lugs, with recesses between them for receiving the pintlelugs of the cover, With the pintle of the hinge, a spring secured to the cover, and a seat or bearing-surface for the spring on the middle pintle-lug, back of the pintle, substantially as and for thepurposes described.

4. A cover for jug-tops, having a recess for receiving and retaining a loose spiral spring placed in said recesss, said spring being provided with an end bearing-disk placed at one side of the center, in combination with a ringsection having a seat or bearing for the spring,

substantially as and for the purposes described.

5. In a jug-top, a hinged cover provided with a spiral spring, in combination with a ring-section having an abutment placed back of the pintle, and affording a bearingor seat for the spring on both its front and rear sides, substantially as and for the purposes described.

In testimony whereof I have hereunto set my hand this 8th day of February. A. D. 1883.
